I managed to sell my bike on Quikr so clearly it works. Indian business face trust issues by default.
"Time tested." lol. Many laws in India date from the times of British Raj, and were outdated even then! -http://www.bbc.com/news/world-asia-india-29516976
When it comes to US constitution, the 1st amendment is the stricter condition that each and every other law should meet. Any law passed that is not consistent with 1st amendment thus becomes invalid.
Opposite is the case with Indian constitution. All the rights given by Indian constitution are totally subject to other laws passed by Indian government. Which means "freedom of expression" is a right as long as no other law prevents it. So basically government can deny you that right any time and in any case it wants.
There are total 8 grounds on which a government can pass a law to further lower the freedom of speech. These 8 grounds cover almost every possible case.
The 1st amendment to US constitution gives people freedom of speech and ensures that government can not pass any laws against it. On the other hand all the "rights" that Indian constitution gives are subject to other government approvals which means you can have Right X to the extent that other existing laws allow.
Despite that several of laws except the IT laws are pretty good and time tested. IT law however is horrible and puts a prohibitive cost on various IT businesses.
Indian classified company Quikr (like CraigList) has hired 200 people just to screen each and every post to make sure it is not "offensive".
